why is beryllium-8 different from beryllium-9 in terms of the nuclear particles?

Answers

Answer:

Beryllium-8 (8Be, Be-8) is a radionuclide with 4 neutrons and 4 protons. It is an unbound resonance and nominally an isotope of beryllium. It decays into two alpha particles with a half-life on the order of 10−16 seconds; this has important ramifications in stellar nucleosynthesis as it creates a bottleneck in the creation of heavier chemical elements. The properties of 8Be have also led to speculation on the fine tuning of the Universe, and theoretical investigations on cosmological evolution had 8Be been stable.

Answers

Answer:

,

Explanation:

Answer:

An atom is the smallest partical in the universe that makes up everything you see around you. Every chemical element is also made up of atoms. Since atoms are what give each element their defining characteristics, each element can be composed of multiple atoms but you must have all of the same type of atoms combined in order for it to be considered an element. For example the element gold can only contain gold atoms. If you mix the atoms of one element with the atoms of another your substance has then been changed from an element to a compound.

A student was adding baking soda and vinegar in a bottle. They then put a balloon on top of the bottle immediately after adding them together. The student observed that the balloon inflated and got larger. The student then predicted that the chemical reaction between the vinegar and the baking soda had created brand new matter, and would have more mass at the end of the reaction. Would you agree with the student’s prediction or not? Explain your answer.

Whoever answers my question gets BRAINLIEST!!

Answers

Answer:

The prediction of the student about the amount of reactant and product is incorrect.

No, I do not agree with the student’s prediction because the amount of reactant is always equals to the amount of product. According to the Law of Conservation of Mass, mass cannot be created nor destroyed. Therefore in any chemical reaction the mass of the products must equal or same to the mass of the reactants so according to this law, the prediction of the student is incorrect.

Explanation:Give brailiest please

Answer:

The chemical reaction that occurs when vinegar and baking soda (sodium bicarbonate) are combined, creates a gas that is known as carbon dioxide (or CO2). I would agree with the student's prediction because the atoms rearrange themselves to create the product.

Use the equation to answer the question.

CH4 + _____Cl2 → CCl4 + _____HCl

Which numbers balance this equation?

Answers

The whole Balanced Reactions Quick Check for Honors Chemistry A is

1) A. The reactants and products have the same number and type of atoms, but the atoms may be recombined.

2) B. It shows how many molecules there are of a particular substance.

3) D. NaOH + HCl → NaCl + H2O

4) A. Atoms always remain intact during chemical reactions.

5) D. 4, 4

The balanced chemical equation is:

CH₄ + 4Cl₂ —> CCl₄ + 4HCl

The numbers that balanced the equation are: 4, 4

To know the number that balanced the equation, we shall simply balance the equation.

CH₄ + Cl₂ —> CCl₄ + HCl

There are 4 atoms of H on the left side and 1 atom on the right side. It can be balance by writing 4 before HCl as shown below:

CH₄ + Cl₂ —> CCl₄ + 4HCl

There are 2 atoms of Cl on the left side and a total of 8 atoms on the right side. It can be balance by writing 4 before Cl₂ as shown below:

CH₄ + 4Cl₂ —> CCl₄ + 4HCl

Now, the equation is balanced

The numbers that balanced the equation are 4,4

Que instrumentos de laboratorio usaron luis y Juan?


Luis y Juan querían hacer una investigación sobre la rapidez de disolución de una pastilla efervescente en el ácido acético a temperatura caliente. Para esto, tenían que triturar la pastilla y luego utilizar solamente 15 gramos de la sustancia. Tenían que medir 50 ml de ácido acético y colocar el mismo en un recipiente donde se pueda calentar sustancias, pero que el vapor generado se libere rápido. Al agregar ambas sustancias al recipiente de vidrio, lo comenzaron a calentar. Una vez se iba calentando, agitaron las sustancias poco a poco y con mucho cuidado, tomaron los cambios en temperatura de cada 2 minutos. Al finalizar el experimento, ellos compartieron sus resultados con sus compañeros de clase.

What does it mean to say that a wave is cyclic, or periodic, disturbance?

Answers

Answer:

Wave is a disturbance or energy that propagate through medium from one point to other point

So basically it is a flowing energy that flows into the medium and hence medium particles start oscillating about their mean position to and fro.

This motion of medium particles or this to and fro motion is about their mean position and this will always be cyclic or periodic motion

This means the disturbance or energy continuously flow through the medium such that it will change the position of medium particle and this will be cyclic in order

For an example

y(x,t) = Asin(kx - ωt + φ)

So here above equation of wave is a travelling wave in which displacement of medium particle from its mean position is given by "y"

Now we can see that this disturbance depends upon the sine function and it will repeat its same position after every 2 pi time interval as it is cyclic function for this value

Due to this phenomenon of repetition of its same position we can say that it is disturbance of wave is cyclic.

Why do atoms exchange or share electrons during bonding?

to obtain a full outer electron shell


to attract an ion with the opposite charge


to become neutral


to have eight inner level electrons

Answers

Answer:

to obtain a full outer shell

Explanation:

The atoms of some elements share electrons because this gives them a full valence shell. ... If atoms can't achieve a full outer shell by transferring electrons, they resort to sharing. In this way, each atom can count the shared electrons as part of its own valence shell. This sharing of electrons is covalent bonding.

Atoms generally exchange or share electrons during bonding because they want to obtain a full outer electron shell. Thus, the correct option for this question is A.

What is Chemical bonding?

Chemical bonding may be defined as a type of interaction that is significantly accomplished through the association of atoms into molecules, ions, crystals, and other stable species that make up familiar substances.

According to the context of this question, the atoms of some elements typically transfer their electrons to the other elements in order to achieve a fully filled outermost shell.

If they do not have a tendency of transferring, they follow a different mechanism of sharing their electrons. The sharing of electrons gives rise to the formation of covalent bonding.

Therefore, atoms generally exchange or share electrons during bonding because they want to obtain a full outer electron shell. Thus, the correct option for this question is A.
